file conversion- .mwb to .sql file

Forward Engineering on my Debian installation of workbench did not work. This worked for me to convert .mwb file to .sql file.

In the menu click "Database" and then "Forward engineering" (shortcut CTRL+G).

UPDATE:

Your .mwb file is a proprietary format, which also holds information of the graphical representation in Workbench. Your generated .sql file is a script, which your MySQL server needs to interpret. To create the database you designed via command line write something like this in the console of your choice:

mysql -u yourUser -p yourDatabase < yourFile.sql

You can omit "yourDatabase" when you create it with your script.
